<p>In the single-indexing method, the blades are positioned in a circle on a cutter head, so that all of the blades run through a tooth space to be produced during cutting of a bevel gear. The workpiece is then rotated by one pitch and the continuously rotating cutter head may then cut the next tooth space. Since the blades do not all have their intended shapes and positions, different structures arise on the tooth flanks, which lead to deviations in the pitch measurement. In order to avoid this, a face-milling method is suggested in which the cutter head gets the same angular position around its axis in relation to the tooth space to be produced as for the preceding space. This has the result that all tooth spaces are not more precise overall, but their surface structures are identical and the pitch measurement is thus not falsified.</p> |
